Strength of Stone

This spell grants supernatural strength to the recipient by raising his or her Strength score by 1d4 points or to a minimum of 16, whichever is higher. Each 10% of exceptional Strength counts at 1 point so a character with a Strength of 17 could be raised a high as an 18/30, but no higher. Both the caster and the recipient must be in contact with solid stone or earth when the spell is cast — standing on the ground will do nicely, but flying or swimming will not.
The spell lasts until the duration expires or until the subject loses contact with the earth. Obviously, this can happen in a number of ways, including being picked up or grappled by a larger creature, being knocked through the air by an impact or explosion, or even being magically moved in some fashion.
